After the fault has been corrected, the 'Check Engine' light must be reset by :-

a) Removing battery NEGATIVE lead for about 15 - 30 seconds (but this requires you to re-input the radio security code)

b) With the ignition 'ON', removing the instrument pack 5 amp fuse (# 5 or #6 in the centre fuse block) and when gauge needles 'drop' waiting a further 10 or 15 seconds for the needles to drop once more before replacing the fuse (obviates the need to re-input radio security code)

c) On pre-1992 cars (theoretically), driving the car faster than 19 mph. [Some have reported this not to be the case and must resort to a) or b) above]

If the fault has not been corrected, the 'Check Engine' light will remain illuminated the next time the car is started / driven.

To see code:-

Early cars (pre-1990) - Stop engine by turning key to Position II - do NOT turn key to 'OFF' (The computer does not store codes in memory for display)
